There aren't many manufactures making a 10mm in a 1911.Most are pretty expensive,like kimber.

I bought a G29 last year in 10mm.I was never a Glock fan and I'm not expert on semis.Still,it functions good.It's conceilable and I can hit what I'm aiming at most of the time at reasonable distances.If I were to do it again,I'd buy another Glock.
